Rubber/bitumen - flexibility and resistance to most dilute acids and alkalis.

Preformed film surface - immediate access for same day screeding.

Applications

It is supplied in rolls 1mm thick overall, 1m wide and 30m long (30 sq metres) and is unrolled sticky side down on to blinded hardcore or structural concrete slabs. Waterproof joints are made by overlapping 50mm and firmly rolling surfaces. Applied to top of concrete slab or blinded hardcore, BITUTHENE® 2000 will provide a moisture/vapour proof barrier and radon gas barrier.

Being factory made, thickness of membrane is constant throughout and is not subjected to variations by site labour such as occurs with brush applied materials. BITUTHENE® 2000 is flexible and well capable of bridging shrinkage cracks in the concrete.

Installation

Concrete slab or concrete blinded hardcore shall be surface dry, free from standing water, and laid to a regular surface free from sharp protrusions and hollows. Vertical faces shall be smooth, regular, dry and free from nails and primed with one coat of BITUTHENE® Primer applied by brush or roller, at a rate depending on the porosity of the surface and allowed to dry before the application of the BITUTHENE® 2000. Brickwork must be flush pointed or rendered to provide a smooth surface. BITUTHENE® 2000 shall be laid by peeling back the protective release paper and applying the adhesive face on to the prepared surface. The material should be brushed on to the surface to exclude air. Adjacent rolls are aligned and overlapped 50mm minimum at side and ends and well rolled with a firm pressure using a BITUTHENE® Lap Roller to ensure completed adhesion and continuity between the layers. A guideline is printed on the membrane. Following the application care should be taken to prevent damage by following trades. Damaged areas can be repaired by patching with an oversized patch applied to a clean, dry surface and firmly rolled.
